I updated it to the latest rikomagic firmware and it's successfully rooted. But I can't see the device from my laptop through android developer tool.

In Android/settings/USB, I checked the "Connect to PC" option, and in "Developer Options" I checked "USB debugging".Then I connect the tv box to my laptop. I use "adb devices", but it shows nothing.Where can the problem be?

I just wanted to tell all those ones who having trouble with firmware update using sd card - You can do the same with a DOK (thumb drive) - Just copy the update.zip to the drive root and reboot the mk802 III. Wait for the firmware update confirmation message and confirm (It should take a minute or two until it shows up because the mk802 III automatically copies the update.zip into the internal memory before).

I did it twice (two different updates) and worked great.Of course - you'll need a USB hub so you'll be able to use the DOK and the mouse at the same time.

1) I suspect it's the 1129 firmware then I tried to use the recovery firmware but it broke the device and I have no home screen.2) So I downloaded the recovery tool from w2comp.com and flash it from window xp (found my eeepc which has xp). I shortcuted the 6-7 pins to let windows install driver. Succeeded.3) Followed another thread ("Detailed Rooting Guide") to root it with Moborobo. Succeeded.4) Followed the slatedroid.com to install ubuntu 12.10. Succeeded.

So now I have a wonderful ubuntu running on it and that's the single reason I buy it.

Note: the 1129 firmware might be correctly rooted. But somehow I can not flash the recovery image with the RKAndroidTool, perhaps because the driver doesn't work for windows 7.

I have flashed this firmware onto my new MK802III, the 8gb white version. However I have no wireless-n! It's advertised as supporting 802.11 b/g/n, however Wifi Analyzer shows no 5ghz options at all. Like it doesn't exist.

So Rikomagic, where is my 5ghz wireless-n wifi??

I had problems with mine when updated to the 20121129 firmware. It seemed like the mouse input would get all laggy (almost unusable) when the device was fully loaded (like opening an app, playing a video etc.). Also, where Plex would stream videos perfectly before, it would now only play a few seconds then stop for 5-10 seconds, then play a few more seconds, then stop, then play etc. I managed to roll back to the Nov 15 firmware using this the tool from this post:viewtopic.php?f=9&t=2725I connected the micro usb cable from my MK802 III to the usb of my Win 7 laptop, then put the MK802 into "Connect to PC" mode from the settings. I also made sure USB Debugging was turned OFF. The computer then detected it, and I told it to install the drivers that was located in the "Drivers" sub folder of what I downloaded from that other post.A few more tips: On the Batch tool, the first button at the bottom is Language, so click it then choose the second option to put it in english. I loaded the .img file that came with the download as it was the Nov 15 firmware in img form. Once the drivers were installed and the device recognized by the Batch tool, I pressed the "Switch" button which put my MK802 into recovery mode I think, then I pressed the "Upgrade" button a bit later and it flashed the firmware.Now my device is working perfectly with mouse and Plex plays flawlessly without encoding over wifi (even my 20GB Avatar rip).
